I'd love to see Kul Tiras. Not a big fan of the old god stuff though. There's other things in WoW lore I find more interesting. But at least Old Gods stuff gives us more potential for Dark Iron Dwarf lore (seriously, I wanna see more Moira Thaurissan on the screen), so there's that. Moira is also the one who sends you on the quest to fetch the shadow artifact in Legion so....
